Background

ArcelorMittal Hamburg steel plant is located in Germany's largest sea port. It consists of direct reduced iron-based Midrex plant, an electric arc furnace, two ladle furnaces, a continuous caster, and a two-strand wire rod mill.[1]

In September 2019, ArcelorMittal announced plans to work with Midrex Technologies to design the Hamburg demonstration plant to produce direct reduced iron in a DRI plant fed with natural gas (methane) with a capacity of 100 ttpa. The plant should be able to switch to hydrogen-based DRI when it is available in sufficient quantities at affordable prices.[2] This demonstration plant is set to start operations in 2026.[3] With the help of this pilot plant ArcelorMittal plans to increase capacity with a full scale plant using this technology by 2030. The full scale plant is envisaged to have a capacity of 600 ttpa, and the short-time work has already begun at the site as of October 2022.[4] Additionally, the plant plans to convert existing DRI plant to use green hydrogen, aiming to produce 1 mtpa of fossil-free steel by 2030, saving 800 ttpa of carbon emissions.[5]

In 2021 it was announced that ArcelorMittal had plans to build a 50 megawatt electrolyser to produce green hydrogen for use in the current and announced DRIs.[6] The eletrolyser was expected to begin operation by the end of 2025, however there has not been any news regarding its construction.

In 2023, the plant dealt with several shutdowns due to low market demand for steel and high electricity costs.[7] Additionally, ArcelorMittal has cancelled other DRI-EAF transition plans for their Bremen and Eisenhüttenstadt plants due to concerns over high electricity cost.[8] However, there has not been an announced cancellation of the announced DRI plans for the Hamburg plant as of November, 2025.
